  "message": "sched: add sched-domain roots\n\nWe add the notion of a root-domain which will be used later to rescope\nglobal variables to per-domain variables.  Each exclusive cpuset\nessentially defines an island domain by fully partitioning the member cpus\nfrom any other cpuset.  However, we currently still maintain some\npolicy/state as global variables which transcend all cpusets.  Consider,\nfor instance, rt-overload state.\n\nWhenever a new exclusive cpuset is created, we also create a new\nroot-domain object and move each cpu member to the root-domain\u0027s span.\nBy default the system creates a single root-domain with all cpus as\nmembers (mimicking the global state we have today).\n\nWe add some plumbing for storing class specific data in our root-domain.\nWhenever a RQ is switching root-domains (because of repartitioning) we\ngive each sched_class the opportunity to remove any state from its old\ndomain and add state to the new one.  This logic doesn\u0027t have any clients\nyet but it will later in the series.\n\nSigned-off-by: Gregory Haskins \u003cghaskins@novell.com\u003e\nCC: Christoph Lameter \u003cclameter@sgi.com\u003e\nCC: Paul Jackson \u003cpj@sgi.com\u003e\nCC: Simon Derr \u003csimon.derr@bull.net\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
